Are there cockroaches in the UK?
Yes. The two most common UK species are:
- German cockroach. Small, light brown, about 1.5cm long, with two dark stripes behind the head. It breeds extremely quickly and prefers warm, humid places such as kitchens
- Oriental cockroach. Larger, glossy dark brown or black, about 2.5cm long, often found in basements, drains and bin areas
Signs of cockroaches
- Live cockroaches, especially at night
- Droppings that look like coffee grounds or ground pepper
- Egg cases, small brown capsules
- A musty, oily smell in heavy infestations
- Shed skins and smear marks
What attracts cockroaches?
They look for warmth, moisture and food, so crumbs, grease, spills, open bins, leaking pipes and cluttered storage areas all invite them. They can also arrive in boxes, deliveries and second-hand appliances, or move between flats and neighbouring properties.
How to get rid of cockroaches
- Clean thoroughly. Wipe surfaces, clean behind and under appliances, and remove grease and crumbs
- Remove food and water. Seal food, empty bins often and fix leaks
- Block entry points. Seal gaps around pipes, skirting boards and cupboards
- Use gel baits. Place small amounts of gel bait in areas where you see activity. Baits are often more effective than sprays
- Avoid foggers and bombs. They can scatter cockroaches deeper into the building rather than killing them
DIY treatment can work for very small problems, but cockroaches are tough to remove completely.
When to call a professional
Call an expert if you see cockroaches repeatedly, if you see them in daylight, if you live in a flat or share walls with neighbours, or if you run a business. For food businesses, cockroaches are a serious hygiene risk that needs prompt, documented action. A professional will identify the species, find where they are hiding and treat the whole area. If you are comparing providers, see pest control vs exterminator, and for pricing see how much pest control costs in the UK.
Health risks
Cockroaches can spread bacteria that cause food poisoning and may trigger allergies and asthma, particularly in children.
Frequently asked questions
Are cockroaches a sign of a dirty home?
Not always. They can arrive in clean homes through deliveries, shared walls and drains, but crumbs and grease help them thrive.
Can cockroaches fly?
Some species can, but the common UK species usually run rather than fly.
How quickly can cockroaches breed?
Very quickly. A single German cockroach can produce many offspring, so early action matters.
